Sometimes proteins in some foods can cause allergic reactions. The reaction happens soon after you have had that food, usually within 2 hours. Sometimes you and your doctor can find out what you are reacting to.

Most common food allergies for children

Cow's milk. Sorry but this could also mean you react to cream, cheese, ice cream and even chocolate!

Eggs (maybe cakes and biscuits too)

Peanuts

Fish and shellfish

Soy beans, soy milk, soy flour

Wheat (bread, cakes, biscuits)

Some berry fruits like strawberries

Gluten - a protein found in cereals like wheat, barley, rye and oats.

Food poisoning is not an allergy. It is caused by germs in food.

What happens if you are allergic to some foods?

You may get a rash around your mouth where food has touched your skin.

You could get hives (an itchy rash on other parts of your body).

You could feel really sick and vomit (throw up).

You could swell up inside your mouth or throat, making it hard to swallow or breathe.

If you don't feel better, mum or dad may ring up the health centre or take you to see the doctor.

Talk to your doctor about what you ate before the reaction. Your doctor might advise you to avoid some foods in the future.

Some people can have such a severe reaction to some foods, such as peanuts, that they need immediate medical help. If you are having problems breathing and your face and neck are swelling then your closest adult should call an ambulance. Have a look at the topic 'Anaphylaxis - when an allergy can be really dangerous' to learn more.

If you keep getting allergic reactions that might be caused by food, see your doctor.
